Stretches to lengthen the Rhomboid muscles between the shoulder blades can greatly assist in the reduction of tension in these muscles. For example: shoulder roll stretches, and simple rhomboid stretches (see Entegra Health Stretch Library here). Stretches to reduce tension in the Pectoral muscles in the anterior (front) muscles of the chest may also assist the reduction of tension in the upper back and Rhomboid area.
Many simple stretches exist to effectively lengthen and reduce tension in the Pectoral muscles of the chest, requiring little equipment other than a wall or doorframe (see Entegra Health stretch library). Stretching the pecs also assists in the reduction of tension in the Rhomboid muscles, located posteriorly in the upper thoracic (back) area.
